CAR-COUPLING.

Specification of Letters Patent.

Application filed .Tune 17, 1914. Serial No. 845,512.

To all whom it may concern.'

Be it known that I, ROBERT Anouar, a citizen of the United States, residing at the city of Brooklyn, county of Kings, and State of New York, have invented a new and useful Improved Car-Coupling, of which the following is a specification.

This invention relates to a car coupling of novel construction, which can be readily manipulated, and securely secures the cars against accidental parting, even when subjected to abnormal strain.

In the accompanying drawing: Figure 1 is a plan of a car coupling embodying my invention, Fig. 2 a vertical central section partly in plan; Fig. 3 a horizontalsection through the female member, `with some of the parts omitted, and Figli an end View of the female member.

The platform 10 carrying the female inember of the coupling, is provided with a bed plate 11, having a longitudinal slot 12. To plate 11, there is attached at 13, the undercut rear end of a tube 14, which extends along slot 12, andis divided at its front end by means of a. number of longitudinal slits into a plurality of spring jaws 15. These jaws have a normal tendency to` diverge from each other at their free ends where they are furnished with beveled hooks 16. Jaws 15 are encompassed by a flanged tubular casing 17, which is attached to plate 11 by straps 18 and is sunk with its lower` portion into slot 12. Between jaws 15 and casing 17, there is interposed a tubular slide 19, which when pushed forward will con tract or close the jaws, while when pushed backward, will permit the jaws to expand or open. In order to operate the slide it is provided with an integral rack 20, projecting outwardly through a corresponding slot of casing 17 and engagedby a pinion 21. This pinion is fast on a shaft 22, stepped into a bearing 23 and carrying a hand bar Pinion 21 is in turn adapted to be engaged by a pivoted pawl 25, provided with a heel 26. A spring 27, bearing against the pawl normally forces it into engagement with pinion 21, and thus locks the latter against rotation. In order to withdraw the pawl front` the pinion, there is provided a cam 28, engaging heel 26, and fast on a shaft 29 which is stepped into plate 11, and carries a hand bar 30.

The platform 31 of the male member of i the coupling,

is provided with a bed plate 32, having a longitudinal slot 33. The taper* ing coupling bar 34, is undercut at its rear end as at 35, and is here pivoted to plate 32 at 36, while the forward end of the bar is accommodated within slot 33. The diameter of the bar is considerably lessthan that of the slot, so that the bar has a lateral play within the latter. Against opposite sides of bar 34E, bear a pair of springs 37 fastened at their rear ends to plate 32 as at 38, and having a tendency to normally center the bar. The front of bar 31 is reduced to form a neck 39, furnished with a head 40, which is adapted to pass between the beveled hooks 16 of spring jaws 15 so as to become interlocked therewith.

The operation of the device will be readily i understood: When slide 19 is in its retracted position, jaws 15 are expanded and head l0 is free to enter between the same.

Pawl 25 being held out of engagement with pinion 21, by means of cam 28, the pinion is turned by shaft 22 to advance the slide and thereby contract the jaws around head 40, thus closing the coupling. Cam 28 is now turned by its shaft 29v to clear heel 26 and thus permit spring 27 to throw the pawl into i "engagement with the pinion, thus locking the same and consequently slide 19. In this way the coupling is positively locked against accidental opening. To open the coupling, pawl 25 is again withdrawn by cam 28, and then the pinion 21 is turned to retract slide 19, thus causing the jaws 15 to open and permitting coupling head 40 to be withdrawn.

I claim- A car coupling comprising a tube adapted to be secured to a car platform and slitted at one end to form a plurality of spring jaws, a slide encompassing said tube and adapted to contract the jaws thereof, a rack integral with the slide, a manually operable `pinion engaging the rack, a pivoted springinfluenced pawl adapted to engage and lock the pinion, said pawl being provided with a heel, and a cam adapted to engage said heel and swing said pawl out of engagement with the pinion. whereby said pinion is adapted to be unlocked.
